Drafted at No. 27 in the 2018 NBA Draft by the Celtics after slipping from a projected lottery position due to concerns over his professionalism and motor, the young center got off to a rough start the day after being drafted, oversleeping for his introductory presser.

But since then, the narrative has (thankfully) gone another direction, with reports that he's been in the gym early every morning, has linked up with the most professional of pros, Al Horford, as a mentor, and has fully embraced the team's well-known high-intensity work ethic.

NBC Boston's Abby Chin sat down with "Boo Butt", as he's sometimes called (just don't call him Bob or Bobby), so watch the video below to hear what they had to say about his new home and teammates.
